1. Introduction The NUGEN Audio AMB system is an off-line file based audio analysis and processing program designed for rapid management of audio content. A variety of processing modules are available to meet your processing needs: 1. Loudness analysis and correction processing designed for rapid assessment and correction of files for loudness and true-peak content to ITU-R BS.1770 (revisions 0-3), and EBU R128 based specifications. 2. Upmixing for generating 5.1 and 7.
2. 2.1 Interface General Layout The interface is designed to facilitate intuitive operation by following a logical flow from top to bottom, left to right, grouping similar aspects of operation into distinct zones as shown below. The interface can be resized using the standard corner drag and maximise/restore functions. You can also resize the various panels by dragging the = symbol in the gaps between them. 1. Drop-down menus File Load Settings... Save Settings Save Settings As... Load Workspace...
queues will be restored. 2. Queue Tabs. Each tab represents the items in a queue. You can double-click the tab to display the settings for that queue. Click on the X button within the tab to close the queue (and stop processing items in it) - it will be removed from the workspace. With a tab selected, only the items in the selected queue are visible. Initially, the name of the tab will be automatically generated.
Files may also be added to the queue using the ‘Add to queue’ option in the File drop-down menu, or added automatically using the watched folder option in the settings dialog. Options are also available here to adjust the results column display. If you have multiple queues active, and you have the ’All Queues’ tab active, adding files will add them to all queues. Clicking on a file updates the log and graph windows to display the corresponding information.
2.5 Settings The settings are split into two categories. Those that affect AMB as a whole (Global Settings) and those that affect only the currently selected queue. You can open the Global Settings from the Settings menu. To open the settings for a specific queue, either double-click on the tab for the queue, or single-click on the tab and then select Settings->Edit Settings... from the menu.
a file called test.L.wav, then AMB will also search for test.R.wav etc. AMB will only process de-interleaved files if all of a ’set’ are present. You must have L+R or 5.1 or 7.1 channels in order to continue. 9. Theme. This allows you to choose the ’look’ of AMB. 10. Feedback level. AMB can report back information about the kinds of files and processes you are performing and the time those processes take.
6. DynApt™ . This control will be ticked if you have a license for the NUGEN Audio DynApt™ expansion. This can be used to alter the dynamics of a file to meet loudness requirements or to re-purpose audio from cinema to TV to podcast (for example). 7. Maximum number of threads. By default, AMB will process files using two threads. This means that up to two files can be processed simultaneously.
(e) Correct Into Folder path. With auto-correct turned on, this folder specifies where corrected files are placed after processing. (f) Corrected files suffix. Type a suffix to be appended to corrected files here to make corrected files easier to identify if required. (g) Routing. Click on the settings button to specify how files with different numbers of channels are handled. i. You can configure the routing based on the number of channels in the incoming file. ii.
(a) Process unsupported files as WAV. With this tick-box ticked, any MXF file that is not in a supported format will be converted to a WAV and processed in the same way that other non-native files are processed. If you un-tick this box then non-supported MXF files will trigger a failure. AMB supports the OP-1a and OP-Atom operating patterns, and any audio in the file must be in either PCM or D10/AES3 format. (b) Update Metadata.
tracks that it is receiving. These options allow you to specify the layout based on the R123 standard.

only contain channel counts where the routing includes at least one stereo and one surround stream. With the number of channels selected, select the radio buttons next to the desrired stereo source and surround target. 4. New File. With this radio button selected, files will be upmixed to a new file. Loudness This tab allows you to configure all of the options related to analysis and correction of loudness parameters. 1.
(b) Algorithm Settings Clicking on this button opens up another display where you can tweak the values of the selected algorithm. Note that if you adjust any of these values then the Algorithm setting in the main page will display ’custom’. i. Short Term Sliding Window This is the period over which the short-term loudness is calculated. You should only change this if your delivery specifically states a different value. ii. Algorithm This is the actual algorithm to use. iii.
(i) Max Short-term Loudness.3 Sets the target value for MaxS. Overall file level will be reduced to ensure this target value is not exceeded. This setting is unavailable if DynApt™ is turned on - use the Max Short-term Above Int option instead. 5. Dynamics Adaptation With the exception of the LRA test criteria, this section is disabled unless you have purchased and activated a valid license for the DynApt™ add-on.
1. Logging Logging can be enabled to store a history of what has happened to a file whilst it has been processed. (a) Daily Log Files. With this option selected, AMB will generate log files where the name is the current date. This way, any work that is performed is grouped based on the day it was done. (b) Separate logs per file. With this option selected, AMB will use the name of the file being processed as a base for the log file name. (c) Export Text Log.
3. Command-line interface AMB does not support a command-line interface at this time. 17 © 2016 NUGEN Audio www.nugenaudio.
4. File exclusion list The file exclusion list is a list of file types (file extensions) that AMB will automatically ignore. This will speed operation and avoid AMB listing ‘unsupported’ files in the processing queue. This list is contained within the file “ExcludeExtns.txt” which can be found in the AMB install directory, and can be manually edited to add/remove file exclusions to suit your operational requirements. By default: On OSX ExcludeExtns.
